Patented July 22, 1930 UNITED stares PAUL RAMY, or BnUssELs, BELGIUM DEVICE FOR SECURING RAILWAY RAILS TO THEIR SLEEPERS Application filed April 3@, 1829, Serial No. 359,205, and in Spain May 3, 1928.

This invention relates to a device for securing railway rails to their wooden sleepers. It has for its object to provide a device which gives the possibility of securing directly the rails to their sleepers by means of spikes or screws and which at the same time ensures a complete immobility of the rail in the direction at right angles'to the axis of the railway road whilst, nevertheless possessing a much greater resistance to thecanting or tilting over than till now.

This device is based on already known devices, on the use of contact plates bearing against the flange of the rail. and on which the spikes rest at the moment of their tightening into the sleeper.

Many systems of this kind have already been suggested. However they have not given good results, as indeed generally the 29 contact plate does not give a good support for the flange of the rail and for the spike and, when the spike is tightened into the sleeper, may be displaced or removed from the flange of the rail, the locking of which is no longer ensured. This inconvenience takes place also in contact plates provided with spurs or acute edges which penetrate into the sleeper in order to produce the anchoring of the plate.

Those bad results must be attributed, as it has been shown by the experiments of the inventor, to the fact that mostly the projection or spur provided on the plate tends to remove the latter from the flange at the moment of its introduction into the sleeper,

When the spike is tightened again. -Moreover in all the systems now in use it happensvery often that at the moment ofthe putting into place, the contact plate was not in a position exactly parallel to the flange of the rail, the

consequence of which was a defective mounting which did not allow the contact plate to give all thedesired results.

This invention has 'for its object to avoid all these inconveniences. A further object also consists in providing improved means for facilitating the mounting of the plates.

With these objects in view the invention essentially consists in the special arrangements and combinations of parts hereinafter fully described and pended claims.

On the accompanying drawings:

Figs. 1 and 2 show respectively a cross section and a top view of a contact plate as constructed according to the invention.

Fig. 3 shows the cooperation of the different parts by which the rail is secured.

Figs. 4: and 5 are detail views showing a key cooperating with the contact plate, at the mounting.

Figs. 6 and 7 show how the contact plates are manufactured in practice.

As shown on Figs. 1 to 8 in the case of the'present invention there is made use'of contact plates 1 provided with a flange or spur 2, the inner face 3 of which is at right angles or substantially at right angles to the lower face 4 of the plate whilst the outer face 5 forms with the upper face 6, an anglewhich is less than The two faces 3 and 5 form an acute edge which is slightly rounded so as to oppose a certain resistance to the introduction into the sleeper. The plate 1 is pointed out in the approvided with a notch 7 for the passage of a spike 8 (Fig. 3) when the latter is tightened into the sleeper. Moreover the branches 9 of the plate surrounding the notch 7 are provided with projections or spurs 10 forming at-the end of the plate opposite to the flange 2 resisting surfaces 11 by which the plates bear against the edge 12 of the rail 13 whilst the flange 2 rests by its rounded edge on the sleeper 14 into which it is introduced gradually when the spike 8 is tightened into the sleeper. Under those conditions, if the contact plate is suitably placed, the inclined face 5 of the flange 2 produces a pressure of the resisting surfaces 11 against the flange of the rail. However, as this pressure can only be efliciently exerted when the contact plate bears by the whole length of the resisting surfaces 11 on the rail flange, there is used for the putting into place of the plate, as shown on Fig. 3, a special key 15 shown separately on Figs. 4: and 5. This key is provided with a notch 16, the dimensions of which correspond to those of the contact plate, in order to be adapted to embrace the latter by vits lat eral branches 17.

This key is also provided with a spur 18 formed in the same way as the flange 2 of the contact plate.

lVhen the contact plate and the key 15 are placed in the position shown on 3, the workman, who tightens the spike by means of the usual wrench 19 must hold the key 15 in its place in exerting a pressure on the end of the key 15 by means of the sole 20 of his boot which rests on the sleeper by the heel 21. The workman could also exert a pressure by the heel of his boot on the key 15 in order to introduce the latter into the sleeper by the flange 2.

During this pressure on the key 15, the sprr 18 holds the bearing faces of the con J 1 tact plate against the Range of the ltlll avoict ing in this way any deviation of the contact plate which could interfere with its contact on its whole length with the edge of the flange of the rail.

It is then only necessary to tighten the spike 8 in order to secure the contact plate. The key 15 is removed as soon as the spike has been tightened.

When the device 11 reabove described is used, the contact plates are put into place without any difficulty and it is impossible for them to deviate from their position. They produce then a pressure against the flange of the rail and the spur avoids any displacement in the direction at right angles to the rail. If, after a more or less long time, the rail is depressed into the sleeper, the gap or space may be compensated by tightening again the spikes, till the contact plate is again applied horizontally on the sleeper and its upper face is situated at the same level with the upper face of the flange 0f the rail.

The contact plates are preferably manufactured from a bar 22 (Figs. 6 and 7) having a profile corresponding to the profile of the contact plates. This bar is introduced into a press provided with shears which cut successively the contact plates according to line 93 at the end of the bar receiving an intermitt nt advancing movement. Simultaneously or successively the openings 7 through which the spikes must pass, are pressed by the punch of the press.

lVhat I claim is:

1. In railway of rails and wood sleepan angle of less than degrees to the top face of the plate and having its other face at an angle of 90 degrees to the said top face of the plate, the latter being further provided, on its face coming into contact with the rail, with flanges forming resting surfaces by means of which the contact plate is applied against the rail flange.

2. In a railway of rails, wood sleepers and spikes anchoring the rails to the sleepers, the combination therewith of contact plates disposed in contact with the flange of the rail without overlapping the latter and provided with a slot open at one side of the plate to receive a rail spike, the said plate being further provided on its face coming into contact with the rail, with a flange forming a bearing surface by means of which the contact plate is applied against the rail flange, and means whereby a space is left between the lower face of the plate and the sleeper, whereby further tightening of the spikes is allowed when the rail descends in the sleeper.

A contact plate for attaching railway rah to tlltll sleepers, comprising a Hat men be]: h aving a slot open at one side of the plate, to receive a rail spike, a flange at the end of each arm formed by the slot and adapted to rest against the rail flange, each said flange being disposed perpendicular to the plane of the plate and having a beveled inner wall, and a second flange projecting perpendicular to the side of the plate opposite that having the first flange, one face of the second flange being disposed at an angle of less than 90 degrees to the top face of the plate and the other face at an angle of 90 degrees to the said top face of the plate.

In testimony whereof I have aflixed my signature.
